[Caml-list] Is tuareg crashing for anyone else?

[Hendrik Boom]

I've been using tuareg mode in emacs, and I find it crashing enough to be unusable.  
It seems to happen when I'm editing a typed function argument, such as 
the arguents in:

  let rec read (prio : int) (look : char option) (input : charstream) 
(psf : phrase list) (return : phrase -> char option -> charstream -> 
phrase) =

I'm not sure what it is I'm doing when it crashes.

I'm currently getting by by editing ocaml programs as foo.xx and copying 
them to foo.ml in a Makefile, though uninstalling tuareg might be easier.

Is this a known problem?  Is it just me?

I'm running devuan jessie, with packages opam 1.2.0-1, tuareg1:2.0.7-1, 
and emacs24 23+4.1-5.

do you also observe the crashes with 1:2.0.9-2 from debian ? Upstream
1:2.0.9 fixed a bad interaction with show-paren-mode (debian bug #780805)

But the parentheses around typed parameters could certainly be part of 
the problem.  At least once weren't balanced when it crashed while I was 
editing!

But 1.2.0.9 hasn't made it to jessie yet.

I've installed 2.0.8 from opam to replace 1:2.0.7-1 from jessie.  
Haven't used it long enough to tell.  But if it takes 2.0.9, it won't be 
enough.  Unless opam and jessie are out of sync.  There doesn't 
seem to be a 2.0.9 in opam yet.  2.0.8 was the version 
that opam installed with
       opam install tuareg.

I'll report back when I've had experience with opam's 2.0.8 version.

Describe "crashing".  For me "crashing" means that the program
exits uncleanly (e.g. segmentation violation, core dump, this kind of
thing).  AFAIK this technically cannot happen to Tuareg-mode, so if
that's what happens to you, it's a bug in Emacs rather than in Tuareg-mode.

The problem seems to have disappeared with 2.0.8.  Or I've been luckky 
in not triggering it.

It stopped accepting any data or responding to anything I type.
As if there's an endless loop somewhere.

But upgrading tuareg seems to have worked.
